(CNN) -- Two doctors who evaluated Jared Loughner will not be required to appear at a competency hearing later this month for the man accused of killing six people and wounding a U.S. congresswoman and 12 others, attorneys agreed in court documents filed this week.

In papers filed Monday with the U.S. District Court in Arizona, federal prosecutors and defense attorneys agreed not to dispute the findings of Dr. Christina Pietz and Dr. Matthew Carroll. The doctors evaluated Loughner, 22, ahead of a scheduled May 25 competency hearing.

Loughner was indicted in March on 49 counts, including murder and attempted murder, in the January 8 shootings outside a Tucson, Arizona, supermarket in which six people were killed, including a federal judge and a 9-year-old girl. Among the 13 wounded was U.S. Rep. Gabrielle Giffords, D-Arizona, who was shot in the head while hosting the meet-and-greet event for constituents.

Giffords continues to recover, and was in attendance Monday as the space shuttle Endeavour was launched with her husband, astronaut Mark Kelly, in command.
